3 Attention symbol is used in these Instructions to point out risks and dangers to the life and limb of persons and/or damage to connection regulationsPlease note the connection conditions specifi ed by your local electrical power supply utility and the VDE regulations. Your heating control system may be installed and serviced only by appropri-ately authorised specialists. w If the system is not installed professionally, this will involve a risk to life and conditionsIf the system is not installed, commissioned, serviced and repaired professionally, this will render the manufacturer s warranty null and of operating proceduresCertain operating sequences are explained using examples. The statuses of the controller are il-lustrated or described as boxes.

4 The following status can be accessed by operating the operating controls as shown or by performing the operation symbols:) Operate mode-selector switch_ Press ECO key* Press Party key] Press Programming key+ Press Plus key- Press Minus keyNotes y Important information is highlighted with this Doc330 /BM02B Connectable modulesGeneralOperation-control module BM allows convenient entry and display of system parameters1 and heating circuit parameters2 for the heating system in the user s living room. This allows the heating system to be monitored and optimised constantly. Moreover, various additional system control functions can be activated by using an operation-control module. The units which can beprogrammed by a BM are described system controller E6E6 is a heating system controller with convenient operator interface which can control systems with two mixer circuits and one hot-water circuit.

5 The two heating circuits can each be monitored by an operation-control module. In a heating system with E6 controller, all system parameters ( hot-water short-time heating, desired hot-water temperature and mixer running time, ..) and the boiler parameters are enabled only on the E6. These parameters are thus masked on all connected operation-control modules. All heating cir-cuit-specifi c parameters are enabled in the BM. All sensor values and desired values for the boiler and the related heating circuit can be manager KKMH eating systems with boiler cascades up to maximum 9 boilers can be controlled by the cascade manager KKM. The cascade manager must be considered in the same way as an E6 controller in relation to connectable operation-control modules for the two integrated heating module MM1 Mixer module MM1 regulates the desired fl ow temperature of a heating circuit.

6 The BM deter-mines the desired fl ow temperature required for the MM1. The mixer module assigned to the operation-control module must be assigned the same bus ID as the C Dbaa Displayb Hinged control panel coverA Mode-selector switchB ECO switch (interrupting the heating time)C Party switch (prolonging the heating time)D Rotary knob for desired value entry1 desired hot-water temperature 2 heating program and desired room temperatureRendamax Doc330 /BM02B 3 Operation Operating controlsMode selector switchThe operating mode of the heating circuit assigned to the operation-control module can be changed simply by operating the mode-selector switch ). The current operating mode is dis-played as a symbol. The mode-selector switch of the operation-control module is operable only if the connected boiler controller or the connected mixer module is in Automatic mode q.

7 If these units are in other operating modes, the operation-control module accepts the correspondingswitch setting. y If the operating mode is changed, the new setting time takes effect after 5 Frost-protection modeThe controller is switched off. If the actual temperature drops below the frost-protection tempera-ture, the controller operates continuously in Frost-protection Automatic modeAutomatic change from Normal mode to Reduced mode at the programmed switching Normal modeThe controller operates continuously in Normal mode and stabilises the system to the set normaltemperature. The time switch is Reduced modeThe controller operates continuously in Reduced mode and stabilises the system to the set re-duced temperature. The time switch is Summer mode(Hot-water operation)The controller switches the burner on only for hot-water generation.

8 The heating system is switched off continuously (Frost-protection mode).W Service modeAll pumps and burners are switched on. The mixers are moved to position Open ._ ECO keyPressing key _ causes the heating circuit to switch to Reduced mode for 1 hour, regardless of the heating program. If the key is pressed in Reduced mode, the reduced period is prolonged by 1 hour. Each time the key is pressed again, the reduced period is prolonged by a further hour. If times 24 hours are entered, the counter is reset to you press the Party key * , the set interruption is shortened by 1 hour. Pressing the mode-selec-tor switch ) terminates the heating time interruption. The temporary reduction is indicated bysymbol B.* Party keyPressing the Party key * causes the heating circuit to switch to Heating mode with the desired room temperature of the last heating time for 1 hour, regardless of the heating program.

9 If the key is pressed in Heating mode, the heating period is prolonged by one hour. Each time the key is pressed again, the heating period is prolonged by one further hour. If times 24 hours are en-tered, the counter is reset to the ECO key _ is pressed, the set heating time prolongation is shortened byone hour. Pressing the mode-selector switch ) terminates the heating time prolongation. The temporary prolonga-tion of the heating time is indicated by symbol Doc330 /BM02 BCorrecting the desired room temperatureThe correction knob for the desired room temperature allows fast and convenient adaptation of the room temperature to your relevant, personal tastes. Using the rotary knob, it is possible to adjust the programmed desired room temperature of the current heating time by 5 K room tem-perature with no change to the program (see Chapter Parallel shift of heat slopes).

10 This change affects all entered desired values for the three different heating times. It is not shown on the display. The set reduced temperature is not infl uenced by the adaptation. ProgrammingParameter entryOpening the hinged control panel cover causes the operation-control module to switch automati-cally to Information and Programming mode. The operating controls are assigned a new signifi -cance (which can be seen from the printed designations which will now appear beneath the keys).All entries can be made on the basis of the same principle1. Open the hinged cover on the front of the controller; the controller switches to INFO mode. The three keys are then assigned the function printed on the inside of the hinged Choose the required parameter of the current level or another level with keys + Press the Programming key ].
